該儀器采用絕對編碼測角系統(tǒng),最小讀數(shù)達1″,測角精度為2″,支持多次測量取均值功能以減少誤差。配備45mm大孔徑物鏡和30倍放大倍率望遠鏡,成像為正像,視場角1°30′,最短視距1.0米。儀器內(nèi)置電子補償器,可自動修正垂直軸誤差,補償范圍±3′。激光對點器(DT402L型號)支持快速精準對中,適應復雜環(huán)境。雙面液晶顯示屏和RS-232C數(shù)據(jù)接口便于操作和數(shù)據(jù)傳輸。1617
應用場景
DT402系列適用于國家三、四等三角控制測量,以及鐵路、公路、橋梁、水利等工程放樣。在建筑領域可用于大型設備安裝和結(jié)構(gòu)變形監(jiān)測;在地籍與地形測繪中能高效完成坐標測量和定向準直任務。其工作溫度范圍-20℃~+50℃,重量僅4.0kg,兼顧耐用性與便攜性。61518
Product Overview
The FOIF DT402 Electronic Theodolite is a high-precision angle measurement instrument utilizing photoelectric technology for digital angle reading, with automatic data calculation and storage. It is widely used in engineering surveys, construction alignment, and topographic mapping. The compact design integrates advanced electronic compensation to enhance measurement efficiency.16
Key Features
Equipped with an absolute encoding system, it achieves 1″ resolution and 2″ accuracy, supporting multiple-angle averaging for error reduction. The 45mm objective lens and 30x magnification telescope provide erect imaging with a 1°30′ field of view. The built-in electronic compensator corrects vertical axis errors within ±3′. The laser plummet (DT402L model) ensures fast centering, while the dual LCD screens and RS-232C interface facilitate data handling.1727
Applications
Ideal for national control surveys (third/fourth-class triangulation) and infrastructure projects like railways and bridges. It excels in building installation, deformation monitoring, and cadastral surveys. With an operating range of -20℃~+50℃ and 4.0kg weight, it balances robustness and portability for field operations.618
